The optional CompressionQualityFactor element specifies an idealized integer amount of image quality, on a scale from 0 through 100.

Usage

<wscn:CompressionQualityFactor wscn:MustHonor=""                               wscn:Override=""                               wscn:UsedDefault=""
  MustHonor = "xs:string"
  Override = "xs:string"
  UsedDefault = "xs:string">
  text
</wscn:CompressionQualityFactor wscn:MustHonor=""                               wscn:Override=""                               wscn:UsedDefault="">

Remarks

Any lossy compression type uses the integer value to determine the amount of acceptable image loss, where a higher value indicates a higher image quality and a correspondingly larger file size. A value of 100 indicates that the device should use the least amount of compression that it supports to produce the highest image quality possible. Currently, JPEG compression is the only supported lossy compression type.

If the requested image compression type is lossless and MustHonor is not present or is false, the WSD Scan Service should ignore the CompressionQualityFactor element and instead use a value of 100. If the compression type is lossless and MustHonor is true, the WSD Scan Service should reject the ScanTicket element if a value other than 100 is specified.

The client can specify the optional MustHonor attribute only when the CompressionQualityFactor element is contained within a CreateScanJobRequest hierarchy. For more information about MustHonor and its usage, see CreateScanJobRequest.

The WSD Scan Service can specify the optional Override and UsedDefault attributes only when the CompressionQualityFactor element is contained within a DocumentFinalParameters hierarchy. For more information about Override and UsedDefault and their usage, see DocumentFinalParameters.

You can subset the allowed values for this element.
